Re: trnasparent stem function

[Jean-marc LEGRAND]

Thanks, Mats !
That does work and I've achieved what I wanted to do :

\version "2.9"
stemLess = \override Voice.Stem #'transparent = ##t
stemFull = \override Voice.Stem #'transparent = ##f
\score {
      \relative c'' {
            \override Staff.NoteCollision  #'merge-differently-headed = ##f
            <<{\stemDown a2 a4 a} \\ {\stemLess c2 c4 c \stemFull} \\ {\stemUp 
e2 e4 e}>>

            }
      }

Best regards !

JMarc

There's no need for a music function here, why not simply do

stemLess = \once \override Voice.Stem #'transparent = ##t

Also, since you use \once in the previous definition, there's no need
to do a revert later.
